A fixture for presetting cutting tools in the tool holders of a single spindle cam actuated turret lathe whereby set up time is substantially reduced. This invention simulates the position of a workpiece in relation to a turret end-forming tool by the use of the actual turret cam to be used for production. A rigid base with a protruding shaft provides a mount for the turret cam. A first slide, movable in a guideway in the base, has its position determined by a cam follower actuated by the lobes of the turret cam. Forming part of the slide are means to hold a turret tool holder. A second slide, also movable in the guideway, has length determining means and a reference pointer. With appropriate use of the length measuring means, the reference pointer will indicate the proper depth of the tool's shank within the tool holder. By use of a second measuring means on the second slide a tool, such as a boring tool, can be positioned off-center within the tool holder. An attachment permits a similar presetting of circular-forming tools within cross slide holders.
